type of box, usually round, with an extendededge bottom, and providing it with a so-called drum formed of a flange, ring or rim and covered over one end with frangible paper or its equivalent, such ring fitting snugly inside of the round wall of the box-body and the paper covering the powder contained in the drum thus housed in the box.

In some cases, the paper may be transparent, such as the so-called Cellophane, whereby the purchaser or user may obserye the powder before the paper or drum-head is ruptured to render it accessible for use. I

In powder-containing boxes of this style substantial difficulty in the past has been encountered in preventing the powder from sifting out of, or nding egress from,v the box before the paper of the drum has been broken through.

Ordinarily, these boxes are made at a boxmakers factory but are filled with the powder at the plant of the manufacturer or seller of the powder.

The designated disagreeable land objectionable sifting or discharge of some of the powder from the box ordinarily occurs by the powder passing out between the ring of the drum and the side wall of the box in which such drum closely and comparatively tightly tsv.

Various attempts have been made to overcome such annoying and provoking delivery of the powder from its supposedly tight and sealed container.

The manner in which such boxes are lled with the powder has in a measure made the solution of the problem somewhat more difficult.

The drums are placed closed end down ona table with their` open ends up and then they are easily and readily lled with the powder, whereupon the inverted box-bodies are placed over and telescopically assembled with the drums by pressing them down so that the drums enter the bodies, after which the box-covers are applied, thus shielding and protecting the more or less fragile paper drum-heads.

It has been endeavored to glue such powderlled drums in their boxes, but such efforts have not been successful, partly perhaps because it is difficult to use glue in close association with the v powder-filling operation and perhaps partially due to the effect of climatic conditions on the adhesive, not to mention the expensel involved in the cost of the adhesive vand `the application of it, bearing in mind that when these boxes and drums are made in large quantities and the goods must be sold at comparatively small figures in a highly competitive cosmetic line, the cost of production is an important item.

It has also been suggested to use a band of 5 v paraffin on the outer surface of the drum-wall or on the inner surface of the box-body wall to prevent the powder from percolating'out between these two portions of the container, but, regardless of-whether or not such paraffin will accomplish the desired powder-retaining function, its use is not commercially feasible, because when such boxes are displayed in the sunlight or otherwise subjected seven to moderate heat, as in a store Window, the parain melts and destroys the otherwise pleasing appearance of the container.

Other efforts have been exerted to overcome this powder-sifting difficulty, and while the problem at first appears to be a relatively easy one to solve, experience has clearly demonstrated that when all the factors involved in the situation are given due "consideration and weight, the task has been found to be one which has not lent itself to ready solution.

Inasmuch as the open end or mouth of the drum must enter the box-body to effect their assembly, the diameter of such portion of the drum must be sufficiently less than the internal caliber of the box-body to permit their ready and facile tting of the box-body over such end, and, on the other hand, to preclude the powder from sifting out between the drum and box-body wall, the two parts should llt together quite tightly, these two requirements obviously being somewhat in conflict.

To allow the easily accomplished initial fitting of the box-body over the open mouth -end of the drum and to have a tight fit of the greater portion of the drum wall or ring in the box-body, attempts have lbeen made to taper the round drum-wall so that ,ase the telescopic fitting of the two parts proceeds, the drum will lit progressively tighter in the box-body, but experience has shown that in such a construction, by reason of the specified taper, there is a tendency for the drum to work up and to loosen in the box-body.

Accordingly, one of the prime and leading purposes'of the invention is to provide a 'construction which will prevent the escape of the powder and which at the same time is simple in structure and which will not add to the cost of the box.

After considerable investigation, study and experiment, over a period of time, I have at last `discovered that this result is capable of accomplishment. n

Instead of using a tapered or flaring drum ring or body, I preferably, but not necessarily, employ one of substantially uniform diameter and of such size that the companion boxbody can beea'sily fitted over it to bring about the assembly of the 60 two parts with facility and dispatch, and, at a part of the drum-ring near its top paper or other rupturable or frangible cover, it is provided with an external, outstanding rib, desirably hollow, as by corrugating or embossing the drum-ring, which when the drum and box-body are fully and completely fitted together presses outwardly against the inner face of the box-body wall to eifect an adequate seal between the two, such rib or circular projection, especially if hollow, having adequate elasticity or resiliency to conform to inequalities of shape and surface of the parts involved to permit the necessary occlusion whereby to effect the required sealing of the powder against discharge in any degree.

To enable those skilled in this art to fully understandfthe invention from both structural and functional standpoints, in the accompanying drawing, forming a part of this specification and to which reference should be had in connection with the following detailed description, a present preferred embodiment of the invention has been illustrated, and, for simplicity, like reference characters have been employed in the views to designate the same structural parts.

Figure 1 is a plan view of the box-body .and associated powder-containing drum with the boxcover removed; and v Figure 2 is an enlarged cross-section through the complete structure showing the box-cover raised from the box-body.

By reference to these views, it will be apparent that the box-body is composed of the circular or round flange, ring or rim Ii and a bottom ldisc I2, the two parts being covered and united in the usual way by the paper I3, the 4one margin I4 of which is folded over and adhered to the under surface of the bottom I2 and the upper or opposite margin i5 of which is folded over into the mouth of the box-body and adhered to the inner surface of its flange or ring. There is nothing novel in such a box-body, as these have been known and manufactured in large quantities over a period of years.

The box-cover characterized as a whole I6, is made in substantially the same manner, and, accordingly, its specific construction need not be further referred to.

The drum comprises a ring or circular wall I1 of slightly less diameter than the box-body wall Il and of approximately the same height, and a transparent paper drum head or cover I8, the circular margin of whichis folded down over a portion of the external surface of the wall or ring I'I.

A strip of cover paper I9-extends around the drum and is adhered to the part of the wall I'I not covered by the drum-head marginand also adhered to such folded-over margin, whereby the drum-head is secured tightly over the end of the drum and the outer surface of the curved wall ofthe drum presents a finished appearance.

The round wall of the drum, remote from its lower edge, at a point covered by the folded margin of the frangible paper drum-head is embossed to provide an outstanding hollow rib or bead ZI extended completely around the drum.

When the powder-filled drum and box-body are telescopically assembled, this bead or rib presses outwardly against the inner surface of the flange of the box-body and seals the space between the two, so that the discharge of powder at that point is overcome.

This construction, while simple, has remedied a fault in the earlier box structures and apparently performs the required function with entire satisfaction.

The invention as described and claimed is not necessarily limited to the exact details of construction presented and these may be modified 5 within proper limits without departure from the heart and essence of the invention and without the loss or sacrifice of any of its benefits and advantages.

For example, it is not essential that the contin- 10 nous bead or rib be hollow, but the latter characteristic is nevertheless highly desirable. Again, it is not a requisite that such bead be covered by the margin of the drum-head paper or that it be covered by the paper band illustrated and described as extending around the drum.

I claim:
